This fixes the "Authorization header required for API calls" error during vendor onboarding after signup. Changes: - Generate JWT access token on signup completion - Set vendor_token cookie for page navigation - Return access_token in signup response for localStorage - Store vendor_token in localStorage after signup completion - Make clearTokens() context-aware to prevent cross-portal interference - Fix vendor logout to not clear admin/customer tokens 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
